    Regular maintenance - change just the impeller or entire housing too?

    I have a 2006 Mercury MA 30 ELH two-stroke 30HP outboard here that came on an aluminium boat purchased from a deceased estate (don't mind the spider webs, they've been cleaned up now.

    I've got a fairly simple 5.2m fibreglass runabout fitted with a 2002 Mercury 115HP Salt Water series outboard (four cylinder, quad carby, oil injection, 2 stroke) outboard motor. Aside from the motor, there's very little in the way of electronics on it - an old fish finder and a radio for...

    Yamaha FT60BET - engine compression specifications and leaking carburettors

    We have recently purchased a Yamaha FT60BET (4 stroke) outboard which has been in storage for approximately the last eight years. It seems that the outboard was used commercially in it's early years and likely was on a vessel which rarely left the water. Removed the spark plugs and dropped a...

    2001 Mercury 115HP Saltwater - which hole should the gearbox oil come out of?

    Today I drained and refilled the oil in the gearbox on my 2001 Mercury 115HP Saltwater outboard. I refilled it from the bottom drain hole using a hand pump. I undid both top plugs (one is marked 'VENT' and the other 'OIL LEVEL'). When refilling the oil came out of the VENT hole not the OIL LEVEL...

    Converting 2001 Mercury Salt Water Series from 2 cylinder idle to 4 cylinder idle?

    I have a 2002 Mercury 115HP Salt Water series outboard (four cylinder, quad carby, oil injection, 2 stroke). My biggest complaint with the motor is that it idles on only two cylinders (this a Mercury system - not an engine fault) which results in both a rough idle and rough take off when...

    My 2001 Mercury 115HP Salt Water Series (2 stroke 4 cylinder carby self mixing oil outboard) has recently been serviced and carbs tuned - it starts very easily and runs as well as ever. It idles reasonably well too (it's the model that drops to 2 cylinders for idle so sounds a bit rough as to be...

    2001 Mercury 115HP Salt Water Series - maintenance?

    I noticed the other day that there is a hose with a strange connection lying on the bottom of the outboard engine (2001 Mercury 115HP Salt Water Series): Tracing the hose back (it's long) and connects to the brass fittings at the top of the motor: I assume therefore it connects into the...

    I have a 2001 Mercury Salt Water Series 115HP: The lower Unit is not seperating. I have undone 5 nylock nuts, removed the trim tab and corrosion block to check for any more bolts/nuts (I can't find any). It is refusing to budge at all. I have tried knocking with a rubber mallet with no...
